Oregon and Southwest Washington RSV Surveillance

Data is tabulated and published as it is received from the participating laboratories, and thus participating laboratories are relied upon for data integrity.

Reports may be based upon rapid tests, DFA, cultures, and other test types; the test methods vary from laboratory to laboratory. The total number of tests may not reflect the total number of patients tested.

Surveillance begins the first week of October of each year and continues until RSV activity has dissipated.

As defined by CDC, the RSV national and regional season onset is determined by the first of 2 consecutive weeks during which the median percentage of specimens testing positive for RSV antigen is >10%. RSV season offset is the last of 2 consecutive weeks during which the median percentage of positive specimens is <10%.
